Duffey Lake Road: Rohr Lake/Marriot Basin Conditions

Mountain Conditions Report

<p>Spent 3 days camped by Rohr Lake on the Duffey Lake Road (December 20-22) with ACMG guide Dan Robb. Skied around the lake and in the Marriot Basin. Cold nights and clear sunny days</p> <p>Strong outflow winds were observed from the North. Recent storm snow has been widely redistributed in the alpine. Windslabs and wind-effected snow were observed 1800 m and above. In some areas surface snow was stripped down to the Dec 15 crust. We observed one Sz 1.5-2 windlab out of a steep rocky start zone (past 48hrs) and there were some loose dry size 1 running on the Dec 15th crust (with solar input), all on south aspects where the crust is most prominent. Otherwise minimal avalanche observations.</p> <p>About 190 cm of snow at treeline.</p> <p>Below treeline there is plenty of good skiing to be had, argw pprox 50-60 cms of well settled HST overlies Dec 15 melt-freeze crust. This snow was found to be settling out rapidly. Found a hard sudden planar shear on the Facets on Dec 15 interface. Some facetting observed in the late November crust but producing no significant results.</p>
